## About

## What it does
Image Resizer lets you resize an image by sending either a public image URL or an uploaded file, along with the target `width` and `height`. You can choose a direct binary download response or a signed URL response, depending on how you want to handle the resized image in your workflow.

Use the URL endpoints when the source image already lives online, or the multipart endpoints when you need to upload the file from your app. The request body for URL mode only needs `url`; multipart mode requires `image`. In every case, `width` and `height` are required query parameters. Optional query parameters include `output`, `preserve_format`, and `auto_orientation`.

The response matches the endpoint you call: download variants return the resized image as binary data, while link variants return a JSON object containing a `data` URI. That makes this service useful for thumbnail generation, profile-image processing, product image preparation, or any backend flow that needs a fixed-size image without adding image libraries to your stack.
